Risk of accident due to unhitching of the ball coupling during transport.
If the coupling is not fully closed the compressor can become uncoupled from the towing vehi‐
cle and cause an accident.
➤ Check correct coupling.
4. Place the open coupling over the towing vehicle ball hitch.
The weight on the coupling will cause it to audibly close. The coupling locks automatically.
Closing and locking is automatic.
5. Push the handle down to be certain of locking.
The coupling is fully locked when the handle is fully down and can be pushed no further.
6. Check correct coupling.
■ Check that the coupling handle cannot be pushed further down.
■ Check that the locking indicator is protruding and visible.
The locking indicator is not visible.
➤ Lift the handle and uncouple.
➤ Set the coupling back on the towing vehicle ball hitch and push down.
